TWS has become a half-million seller for the second consecutive time.

TWS released their second mini album "SUMMER BEAT!" on the 24th of last month. According to Circle Chart, the new album has sold 554,365 copies (as of 30 June).

With their two albums this year, the group has sold over 1 million copies cumulatively. Their previous mini album, "Sparkling Blue," sold more than 520,000 copies.

Their music is also popular. The title track, "If I'm S, Can You Be My N," entered the Melon Top 100 at No. 94 on the 25th of last month. It soared to No. 26 on the 10th.

Overseas media are also taking notice. The American FOX channel 'Fox 13 Seattle' selected "If I'm S, Can You Be My N," as its 'Summer Soundtrack: K-Pop Song'.

It's a perfect summer song. "Even if you're not familiar with K-pop or don't know Korean, you can enjoy it," it said, explaining that the group is "the best at executing bright concepts."

Meanwhile, TWS will appear on the Grammy Museum's 'Global Spin Live' on the 1st of next month. They will be performing live.
